The problems with typical manufacturing methods when it comes to putting together complicated parts
When it comes to putting together complex parts in energy equipment, traditional manufacturing methods like casting, forging, machining, and welding have a lot of problems. Casting technology can make parts with complicated shapes, but when you put together different elements, you need to build complicated molds and casting systems. Casting errors are likely to happen at the connecting points between different components, which might weaken the whole thing and make it less airtight. Forging technology is mostly utilized to make blanks with simple shapes. It's hard to directly integrate complex parts into these blanks. Mechanical processing is all about changing the shape and size of each item. When you put together a lot of parts, it takes a lot of work, which raises the risk of mistakes and costs. Welding technology can connect parts, but it can also create a heat-affected zone throughout the operation, which can modify the properties of the materials. Also, for some parts with complicated interior systems, it is hard to make sure that the welding is of good quality.
The idea behind metal 3D printing for putting together complicated parts
The idea behind metal 3D printing is additive manufacturing, which builds three-dimensional items by layering metal ingredients on top of each other. The main benefit is that it may use computer-aided design (CAD) models to directly combine the shapes and functions of many parts into one overall structure. During printing, high-energy beams like lasers and electron beams melt and solidify metal powders or wires layer by layer. Each layer melts and solidifies exactly according to the design specifications, thus there is no need for further molds or assembly operations. This way of making things layer by layer makes it easy for metal 3D printing to combine complicated internal structures, uneven surfaces, and many parts, which gives designers a lot more freedom when designing energy equipment parts.
Ways to put together complicated parts in energy equipment
Designing structures that work together
Metal 3D printing lets designers make systems that used to need a lot of separate parts to work together. For instance, gas turbines have distinct blades and discs that are joined by mortise and tenon constructions, which can cause problems with stress concentration and sealing. With metal 3D printing technology, turbine blades and discs may be designed and produced as a single piece, which gets rid of connection pieces, lowers stress concentration, and makes the parts stronger and more reliable overall. At the same time, integrated design can cut down on the number of parts, make equipment lighter and smaller, and make energy equipment work better.
Integration of complex internal flow channels
Energy equipment generally needs complex internal flow channels to do things like cool, heat, or move materials around. It's hard to make parts with complicated interior flow channels using traditional manufacturing methods, but it's easy to do using metal 3D printing. For example, the fuel components of a nuclear reactor need to have complicated cooling channels built into them to get rid of the heat that the fuel rods make. Metal 3D printing technology makes it possible to create complicated cooling channels right into the support structure of fuel assemblies. These channels can be made better and constructed based on how the heat load is spread out. This makes cooling more efficient and keeps nuclear reactors safe.
Integration of components with several functions
Metal 3D printing can also combine several functionalities into one part. Collectors in solar thermal power generation systems need to be able to concentrate, absorb, and exchange heat at the same time. Metal 3D printing technology can be used to make collector parts with unique surface structures and interior channels. The surface structure can improve the concentrating effect, while the inside channels can help with heat absorption and exchange, combining many functions into one part, which makes solar thermal power generating systems work better and more efficiently.
